Description

Technical Field

[0001] This invention relates to the field of plum wine brewing technology, specifically to a plum wine brewing method and equipment. Background Technology

[0002] Traditional plum wine making process is simple. Whether it is soaking or fermenting plum wine, the fruit pits are mixed together in the brewing process, and even the pits are crushed and pulped for production. This brings an unpleasant flavor to the wine. Plum pits contain the following components: (1) Amygdalin, which is a cyanogenic glycoside compound that is widely found in the pits of Rosaceae plants, such as plums, apricots, and peaches. When it enters the human body, amygdalin is decomposed by enzymes to produce hydrocyanic acid (HCN), which is a toxic substance. Excessive intake may lead to poisoning, with symptoms including dizziness, nausea, and vomiting, and in severe cases, it may even endanger life. (2) Tannin, which is a polyphenol compound that exists in the pits and peels of the fruit. Tannin has an astringent taste, and excessive intake may affect digestive function, leading to stomach discomfort or constipation. During fermentation, tannin can make the wine taste astringent and affect the flavor. (3) Lignin, which is a structural component in the pits and belongs to complex organic polymers. Lignin is difficult for the human body to digest and absorb and can affect gastrointestinal function. During fermentation, lignin may increase the turbidity of the wine, affecting its appearance and taste. (4) Oils: The kernel contains a small amount of oil, mainly composed of unsaturated fatty acids. Oils may oxidize during fermentation, producing unpleasant flavors and even generating harmful substances. Oxidation of oils may cause off-flavors in the wine, affecting its quality. (5) Trace heavy metals: The kernel absorbs trace heavy metals (such as lead and cadmium) during growth. Long-term intake may pose potential health risks. The content is usually extremely low, but removing the kernel can reduce this risk.

[0003] Therefore, a pit-removing brewing process for plum wine is currently needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for brewing plum wine, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for brewing plum wine, the method comprising the following steps: S1. Pre-treatment of green plums: Unqualified green plums and impurities are manually removed; the green plum raw materials are cleaned by a bubble washing machine; the cleaned green plums are then dried by an air dryer. S2. Plum pitting: Qualified plums are fed into a pin-type plum pitting machine to remove the pits, and the plum fruits and pits are automatically separated and output. S3. Juicing: A pneumatic screw juicer is used to juice the pitted green plums. The plum juice is then pumped into a refrigerant-controlled temperature fermentation tank by a sealed juice delivery pump. S4. Three-stage gradient fermentation in a fermentation tank. Fermentation ingredients include: plum juice, yeast, and white sugar. The first stage involves controlling the temperature of the fermentation tank at 16℃-20℃ to fully decompose the pectin in the juice and wait for fermentation. The second stage involves controlling the temperature of the fermenter at 18℃-25℃. This stage is the start-up and peak fermentation period.

[0014] This invention provides a method and equipment for brewing plum wine. Compared with the prior art, it has the following advantages: 1. The pitting process is carried out using a pin-type pitting machine. Through pitting, juicing, and fermentation, the juice is free of amygdalin, tannins, lignin, oils, and trace metals found in plum pits, thus maintaining the purity and elegant fruit aroma of the wine. This process also eliminates bitterness and effectively improves the clarity, sensory appeal, and health benefits of the plum wine. The fermentation process employs a three-stage temperature control system, which effectively controls the production of fusel oils and methanol, thereby enhancing the quality of the wine. 2. Fermentation employs a three-stage temperature control: The first stage controls the juice temperature at 16℃-20℃, which is conducive to the effective decomposition of pectin by pectinase at room temperature; it also reduces oxidation of the juice at low temperatures and preserves low-boiling-point aroma compounds. The second stage, at 18℃-25℃, is the temperature for the start and peak fermentation period. Fermentation at this temperature not only preserves the low-boiling-point aroma of the wine but also enhances its mellowness and roundness, and avoids the production of volatile acids during fermentation. The third stage, at 25℃-30℃, retains even more low-boiling-point compounds, ensuring the wine maintains its typical fruity aroma and mellow, rounded character. Attached Figure Description

Example 1

[0018] To overcome the problems existing in the current plum fermentation technology (such as excessive levels of toxic hydrogens, excessive levels of tannins that affect taste and flavor, excessive levels of lignin and oils, and excessive levels of heavy metals); Combination Figure 1 As shown, the present invention provides a method for brewing plum wine, the method comprising the following steps: S1. Pre-treatment of Green Plums: Unqualified green plums and impurities are manually removed; the raw green plums are washed using a bubble washing machine; the washed green plums are then air-dried using a drying machine. S2. Pitting of Green Plums: Qualified green plums are conveyed to a pin-type green plum pitting machine to remove the pits, and the plums and pits are automatically separated and output. S3. Juicing: A pneumatic screw juicer is used to juice the pitted green plums, and the plum juice is pumped into a refrigerant-controlled temperature fermentation tank via a sealed juice transfer pump.

Example 2

[0019] like Figures 2-21 As shown, a plum wine brewing equipment includes a washing machine 710, a drying machine 72, a pin-type pitting machine 100, a pneumatic screw juicer 730, and a fermentation tank 740; the fermentation tank 740 is a refrigerant temperature-controlled fermentation tank with a built-in refrigeration system, and the bottom side wall of the pneumatic screw juicer 730 is connected to a pulp delivery pipe 731 through a juice sealing delivery pump; The impact-type pitting machine 100 includes a base 110, a roller 120, a stamping assembly 170, a feed hopper 130, a first discharge hopper 140, and a second discharge hopper 150. The roller 120 is rotatably mounted on the end face of the base 110. The outer wall of the roller 120 has multiple rows of annularly arranged receiving grooves 121, and the inside of the receiving grooves 121 has a release hole. One side of the roller 120 has a feed hopper 130, and the other side has a first discharge hopper 140. The second discharge hopper 150 is installed inside the roller 120. The stamping assembly 170 is mounted above the roller 120 and is vertically slidably mounted on the end face of the base 110. The inside of the base 110 is a drive assembly 160, which is used to synchronously drive the rotation of the roller 120 and the lifting and lowering of the stamping assembly 170. The output end of the second discharge hopper 150 is provided with a lifting machine 200, and the output end of the lifting machine 200 is connected to the pitting machine 300. The fruit pit peeling machine 300 includes an outer casing 310. A side support 320 is provided on the side wall of the outer casing 310. The side cross-section of the side support 320 is shaped like the number 7. A moving guide rail 330 is provided at the bottom of the outer casing 310 and is fixed to the bottom of the inner wall of the side support 320. An inclined inner box 340 is installed inside the outer casing 310. Two sets of peeling tubes 350 are symmetrically installed inside the inner box 340, with the two sets of peeling tubes 350 fitting together. A feed inlet 311 is opened at the top of the outer casing 310. Converging side plates 341 are symmetrically provided at the top of the inner box 340. The bottoms of the two sets of converging side plates 341 are located between the two sets of peeling tubes 350. The two sets of peeling tubes 350 rotate inward synchronously to peel the fruit from the pit. The feed inlet 311 is located between the two sets of peeling tubes 350. Above the highest point of the 0, each set of peeling tubes 350 has a set of driven gears 352 installed at its outer end. The outer end face of the outer box 310 is provided with a drive gear 370, which meshes with the driven gear 352 located on one side. The bottom of the two sets of peeling tubes 350 is a collection cavity 342. The inner wall of the inner box 340 is symmetrically provided with scrapers 360. The scrapers 360 contact the outer bottom of the peeling tubes 350 and are used to scrape off the residual pulp on the outer wall of the peeling tubes 350. One end of the outer box 310 is provided with a pushing component 400, which is used to push out the peeled pulp in the two sets of peeling tubes 350 and the collection cavity 342. The other end of the outer box 310 is provided with a sorting and exporting component 500, which is used to sort and export the peeled fruit and the peeled pit.

[0020] In the above scheme: 1. The drive component 160 of the impact-type pitting machine synchronously drives the roller 120 to rotate and the stamping component 170 to rise and fall. The receiving groove 121 of the roller 120 is aligned row by row with the punch 175 of the stamping component 170 to achieve precise and continuous stamping and pitting of plums, avoid missed or incorrect stamping, and improve pitting efficiency.

[0021] 2. The two sets of peeling tubes 350 of the pulp peeling machine 300 rotate inward synchronously, cooperating with the gathering side plate 341 to guide the fruit pit to the peeling area. The scraping groove 351 on the outer wall of the peeling tube 350 can efficiently peel off the residual pulp on the surface of the fruit pit. The scraper 360 scrapes off the pulp attached to the outer wall of the peeling tube 350 in real time to ensure thorough peeling. The pushing component 400 drives the inner and outer pushing plates 430 through the drive screw 420 to push the pulp in the peeling tube 350 and the gathering cavity 342 respectively, realizing fully automatic discharge and avoiding pulp residue and spoilage. The sorting and exporting component 500 separates the fruit and the pit exporting cavity 540 through the partition 520. The peeled pulp enters the fruit exporting cavity 530, and the pit enters the pit exporting cavity 540 through the V-shaped exporting tube 550, realizing automatic sorting without manual sorting.

[0022] In this embodiment, the outer wall of the peeling tube 350 is provided with multiple sets of annularly arrayed scraping grooves 351. The scraping grooves 351 are axially extending strip structures. The side cross-section of the scraping grooves 351 is a figure-eight structure with a narrow outer side and a wide inner side. The outer end of the scraping grooves 351 is a cutting edge structure.

[0023] In the above scheme: the scraping groove 351 on the outer wall of the peeling tube 350 is an axially elongated strip structure. The V-shaped design, narrow on the outside and wide on the inside, increases the contact area with the pulp and enhances the peeling force. The blade structure facilitates cutting into the gap between the pulp and the pit, efficiently peeling off residual pulp and reducing adhesion. The inner wall of the V-shaped scraping groove 351 is smooth, and the blade only acts on the pulp, avoiding scratching the pit and introducing woody impurities, ensuring the purity of the peeled pulp and not affecting the subsequent fermentation quality.

[0024] In this embodiment, the stamping assembly 170 includes a pressure frame 171, a lifting seat 172 at the rear end of the pressure frame 171, a lifting groove 111 on the end face of the machine base 110, the lifting seat 172 passing through the lifting groove 111 in a cross shape, and symmetrically arranged sliding sleeves 173 on both sides of the inner end of the lifting seat 172. The sliding sleeves 173 are slidably fitted onto the outside of the guide rod 174. The guide rod 174 is vertically symmetrically arranged on both sides of the inner end of the lifting seat 172 and located inside the machine base 110. The width of the lifting seat 172 is greater than the width of the pressure frame 171. The bottom surface of the pressure frame 171 is provided with multiple sets of punches 175. The driving assembly 160 includes a main motor 161, a driving arm 167, and a driving impeller 168. The output end of the main motor 161 is connected to the output shaft 162. The end is provided with a first inclined plate 163 and a second inclined plate 164. The length of the second inclined plate 164 is greater than the length of the first inclined plate 163. The angle between the first inclined plate 163 and the second inclined plate 164 is 110°-120°. The outer end of the first inclined plate 163 is provided with a first connecting post 165. The bottom end of the drive arm 167 is rotatably connected to the outer end of the first connecting post 165. The top end of the drive arm 167 is rotatably connected to the rear end of the lifting seat 172. The drive impeller 168 is located at the inner end of the drum 120. The outer wall of the drive impeller 168 is provided with grooves 169 arranged in a ring array. The outer end of the second inclined plate 164 is provided with a second connecting post 166. The second connecting post 166 is fitted into the groove 169. The extension directions of the first connecting post 165 and the second connecting post 166 are opposite.

[0025] In the above scheme: the main motor 161 drives the first inclined plate 163 (which drives the stamping assembly 170 to rise and fall via the drive arm 167) and the second inclined plate 164 (which drives the drum 120 to rotate via the drive impeller 168) through the output shaft 162, achieving complete synchronization between the rotation of the drum 120 and the stamping lifting, thus avoiding pitting failure due to misalignment of actions. A single motor replaces a dual motor, simplifying the equipment structure and reducing energy consumption and maintenance costs; the included angle design of the first and second inclined plates (110°-120°) ensures that the rhythm of the two actions is matched, adapting to the processing requirements of pitting plums.

[0026] In this embodiment, the pushing component 400 includes a pushing motor 410, a drive screw 420, an outer pushing plate 430, a first push rod 431, a second push rod 432, a first inner pushing plate 440, and a second inner pushing plate 450.

The inner end of each set of first push rods 431 is connected to a set of first inner pushing plates 440. The first push rod 431 slides through the sliding hole 353 in the middle of the peeling tube 350, and the inner end of the second push rod 432 is fixedly connected to the second inner pushing plate 450.

[0027] In the above scheme: the pusher motor 410 drives the outer pusher plate 430 through the drive screw 420, which simultaneously drives the first pusher rod 431 (pushing the first inner pusher plate 440 inside the peeling tube 350) and the second pusher rod 432 (pushing the second inner pusher plate 450 inside the gathering cavity 342), realizing synchronous discharge of material from the peeling tube 350 and the gathering cavity 342, avoiding fruit pulp residue. The entire process is mechanically automatic, requiring no manual contact and reducing the risk of human contamination; the adaptable structure of the pusher plate with the peeling tube 350 and the gathering cavity 342 ensures thorough discharge and reduces the difficulty of cleaning the equipment.

The inner side of the partition 520 is a fruit exporting cavity 530, and the outer side is a pit exporting cavity 540. The output ends of the two sets of peeling tubes 350 extend to the top of the fruit exporting cavity 530. The outlet end of the gathering cavity 342 is connected to the fruit exporting cavity 530. The bottom of the fruit exporting cavity 530 is connected to a first transfer box 620. The middle top of the partition 520 is provided with a V-shaped exporting tube 550.

The inner side of the pit exporting cavity 540 is inserted into a second transfer box 630.

[0029] In the above scheme: the partition 520 of the receiving box 510 divides the interior into a fruit outlet cavity 530 and a pit outlet cavity 540. The peeled pulp enters the fruit outlet cavity 530 through the output end of the peeling tube 350 and the outlet of the collection cavity 342, while the pit is precisely guided into the pit outlet cavity 540 through the V-shaped outlet tube 550, achieving complete separation of the two. The fruit outlet cavity 530 connects to the first transfer box 620, and the pit outlet cavity 540 is inserted into the second transfer box 630.

[0030] In this embodiment, the open end of the fermenter 740 is covered with a sealing cap. A central storage component is located in the middle of the interior of the fermenter 740. The central storage component 800 includes a horizontal hanging rod 810, an upper tube component 820, and a lower tube component 830. The horizontal hanging rod 810 is horizontally positioned at the top opening of the fermentation tube. A positioning ring 811 is rotatably mounted in the middle of the horizontal hanging rod 810. A square hole is opened inside the positioning ring 811, and the upper tube component 820 is fixed inside the square hole. The lower tube component 830 is installed at the bottom of the upper tube component 820. Two sets of adjusting components 840 are symmetrically installed on the side of the upper tube component 820 to adjust the opening and closing of the lower tube component 830. A pressing component 850 is installed inside the upper tube component 820. The outer wall of the lower tube component 830 has a mesh structure. The central storage assembly 800 includes the following states: In the first state, the lower tube component 830 is in a retracted mode, the lower pressure component 850 is folded inside the upper tube component 820, and the pulp delivery pipe 731 is inserted into the upper tube component 820; the lower tube component 830 and the upper tube component 820 are connected as a single unit to form a temporary storage structure to store the peeled pulp and the pulp output from the pulp delivery pipe 731; in the second state, the lower pressure component 850 unfolds the pulp within the lower pressure temporary storage structure; in the third state, the wine is extracted from the lower pressure component 850; in the fourth state, the lower tube component 830 unfolds to form a blade structure, the lower pressure component 850 is folded inside the upper tube component 820, and the lower pressure component 850 drives the unfolded lower tube component 830 to rotate to agitate the liquid in the fermentation tank 740.

The lower tube component 830 is aligned and connected to the bottom of the upper tube component 820. The pulp and peeled fruit pulp produced by the pneumatic screw juicer 730 can be added into the lower tube component 830. The mesh structure of the lower tube component 830 can filter the pulp, so that the particulate matter in the pulp is trapped in the lower tube component 830. At the same time, the peeled fruit pulp is also stored in the lower tube component 830, which can prevent the particulate matter from settling at the bottom of the fermentation tank 740, so that the dissolution and fermentation efficiency of the particulate matter is higher. During the feeding process, the lower pressing component 850 is lifted and folded into the upper tube component 820 so that the pulp conveying pipe 731 can pass through the lower pressing component 850 for feeding. 2. After the pulp and peeled fruit pulp are added, the pressing component 850 can be used to press and squeeze out more water. At the same time, the pressing component 850 can also compact the fruit pulp particles. During the fermentation process, the compaction of the fruit pulp particles can accelerate the dissolution of the fruit pulp particles, prevent small fruit pulp particles from dispersing, and ensure that the fruit pulp and wine are in full contact and fermentation is uniform.

[0032] 3. During the fermentation process, staff need to check the liquid regularly. The lower tube component 830 can be adjusted to a vertical position. In this way, the lower pressure component 850 can be lifted to bring out the liquid, avoiding contamination by miscellaneous bacteria and facilitating real-time observation of the fermentation status or sampling for testing.

[0033] 4. During the fermentation process, the lower tube component 830 can be folded and stored inside the upper tube component 820. The adjusting component 840 can drive the lower tube component 830 to unfold, thus forming a blade structure. Rotating the pressing component 850 can drive the upper tube component 820 and the lower tube to rotate, thereby agitating the fruit. No additional tools are required, making the operation convenient and not damaging the fermentation environment.

[0034] In this embodiment, the upper tube component 820 includes an upper tube 821, the top end of which is fixed in the square hole of the positioning ring 811.

A sloping movable plate 832 is provided at the top outer wall of the lower square tube 831, and a sloping fixed plate 833 is provided at the bottom outer wall of the upper tube 821. The bottom end of the sloping fixed plate 833 is connected to the sloping movable plate 832. The top of the device is rotatably connected and a meshing gear 834 is provided at the rotatable connection; the adjusting component 840 includes an upper plate 841, a lower slide plate 842, an adjusting screw 843, and a vertical toothed plate 844. The upper plate 841 is horizontally fixed to the side wall of the upper tube 821. The adjusting screw 843 is threaded through the interior of the upper tube 821. The lower slide plate 842 is parallel to the bottom of the upper plate 841. The inner end of the lower slide plate 842 is slidably connected to the upper tube 821. The bottom end of the adjusting screw 843 is rotatably connected to the lower slide plate 842. The bottom surface of the lower slide plate 842 is vertically provided with a vertical toothed plate 844, which meshes with the meshing gear 834.

[0035] In the above scheme: 1. The upper tube 821 and the lower half square tube 831 are designed to guide the vertical movement of the pressing component 850, and the upper tube 821 and the lower half square tube 831 can be rotated by rotating the pressing component 850. 2. The adjusting screw 843 can drive the lower slide plate 842 and the vertical toothed plate 844 to move vertically. The vertical toothed plate 844 can mesh with and drive the driven gear 352 to rotate. The inclined movable plate 832 rotates around the inclined fixed plate 833, thereby driving the lower half square tube 831 to rotate, realizing the opening and closing of the lower half square tube 831.

[0036] In this embodiment, the pressing component 850 includes a pressing cup 851, which has a square cross-section when viewed from above. An insertion hole 852 for inserting a slurry delivery pipe 731 is provided inside the pressing cup 851. A cover plate 853 is rotatably fitted to the bottom of the insertion hole 852, and a torsion spring is installed at the rotatable connection.

A pressing screw 856 is vertically damped and rotatably mounted inside the base 855. A handle 857 is vertically provided at the outer end of the pressing screw 856. In the first state, the two sets of lower square tubes 831 are merged and retracted, and the pressing screw 856 is adjusted to a horizontal state. In the second and third states, the pressing screw 856 is adjusted to a vertical state so that it spirals through the screw hole 823. In the fourth state, the two sets of lower square tubes 831 are tilted and unfolded, and the pressing screw 856 is adjusted to a horizontal state to drive the upper tube 821 to rotate.

[0037] In the above scheme: 1. To achieve the purpose of pressing down fruit pulp particles and scooping up wine samples, a pressure cup 851 is designed. The top of the pressure cup 851 forms a receiving cavity, in which the wine can be stored. The bottom surface of the pressure cup 851 can press down particles. An insertion hole 852 is opened on the bottom surface of the pressure cup 851. The main body of the pulp delivery pipe 731 is a flexible tube, and the front end is a rigid tube. The pulp delivery pipe 731 can be inserted into the insertion hole 852, which will abut against the cover plate 853 and rotate downward. The pulp can then pass through the pressing component 850 and be output normally. The pulp is output into the lower tube component 830, which can filter the pulp. After the liquid is added, the pulp delivery pipe 731 is pulled out, and the cover plate 853 can automatically seal the insertion hole 852 under the action of the torsion spring. 2. The pressing component 850 is designed as a two-section structure. The pressing screw 856 can be rotated and adjusted to a vertical position.

When the pressing screw 856 is pushed down, the threaded section of the outer wall of the pressing screw 856 can be matched with the threaded groove on the inner wall of the insertion hole 852. Rotating the pressing screw 856 will drive the lifting rod 854 to rotate through the base 855, thereby pushing the pressure cup 851 down. The square pressure cup 851 can then press the fruit normally. Meat particles; the pressing screw 856 can also be rotated to a horizontal position, so that the pressing screw 856 is placed parallel to the horizontal hanging rod 810. The rotation of the pressing screw is damped, which can maintain the rotation position. Furthermore, locking screws or locking positioning measures can be added to maintain this state. At the same time, the pressing screw 856 can also form a lever effect when it is horizontal. By operating the manual control handle 857, the pressure cup 851 and the upper tube 821 can be easily rotated.

[0038] Working principle and usage process of this invention: Qualified plums are output to the feed hopper 130 of the impact-type pitting machine, and then dispersed into the receiving groove 121 of the drum 120. The main motor 161 drives the output shaft 162 to rotate, and the output shaft 162 drives the first inclined plate 163 and the second inclined plate 164 to rotate. The first inclined plate 163 swings back and forth through the first connection and the drive arm 167 to drive the lifting seat 172 to move up and down along the guide rod 174. The lifting seat 172 drives the pressure frame 171 to move along the lifting groove 111. The pressure frame 171 drives multiple sets of punches 175 to move up and down synchronously. At the same time, the second inclined plate 164 drives the impeller 168 to rotate through the second connecting column 166, which in turn drives the drum 120 to rotate. In this way, the punches 175 punch the plums in the receiving groove 121 row by row, so that the plum pits fall through the detachment hole to the second discharge hopper 150, and the pitted plums are output to the first discharge hopper 140. Place the transfer box 610 on the moving guide rail 330, remove the baffle at the output end of the first discharge hopper 140, and output the pitted plums into the transfer box 610. The plum pits are fed into the feed inlet 311 of the outer casing 310 by the feeder 200, and then collected at the junction of the top ends of the two sets of peeling tubes 350 by the gathering side plate 341. The drive gear 370 drives the two sets of driven gears 352 to rotate, thereby driving the two sets of peeling tubes 350 to rotate inward synchronously. The peeling tubes 350 extend downward at an angle, and can peel and output the fruit pits at the same time. When the peeling tubes 350 rotate, the scraper 351 can scrape off the pulp on the outside of the fruit pits, and the pulp enters the peeling tubes 350. The scraper 360 can scrape off the pulp attached to the outer wall of the peeling tubes 350, so that the pulp enters the gathering cavity 342. The peeled fruit pits are output to the second transfer box 630 through the outlet tube 550 and the fruit pit outlet cavity 540. After a period of peeling, the push motor drives the drive screw 420 to rotate, the drive screw 420 drives the outer push plate 430 to move, the outer push plate 430 drives the first push rod 431 and the second push rod 432 to move, the first push rod 431 drives the first inner push plate 440 to push the pulp in the peeling tube 350 to the fruit outlet cavity 530, and the second push rod 432 drives the second inner push plate 450 to push the pulp in the gathering cavity 342 to the fruit outlet cavity 530, and finally store it in the first transfer box 620; The pitted green plums in the transfer box 610 are poured into the pneumatic screw juicer 730, which then crushes the pitted green plums into a pulp. Adjust the screw 843 to a horizontal position, insert the pulp delivery pipe 731 into the insertion hole 852, and it will rotate downward against the cover plate 853. The pump body of the pneumatic screw juicer 730 outputs pulp to the pulp delivery pipe 731. Then, the pulp is discharged into the pulp delivery pipe 731, and finally discharged into the temporary storage structure composed of two sets of lower square tubes 831. The lower square tubes 831 filter the pulp, so that the pulp particles are trapped in the temporary storage structure. After the liquid is added, the pulp delivery pipe 731 is pulled out, and the cover plate 853 can automatically seal the insertion hole 852 under the action of the torsion spring. Pull out the pulp delivery pipe 731, cover it with the sealing cap, and adjust the temperature to carry out gradient fermentation; press down the pulp with the pressing component 850 to prevent the small particles of pulp from dispersing during soaking and to accelerate the dissolution rate. During routine inspections, the sealed cap can be opened. During fermentation, the upper and lower pressing components 850 can be lifted to raise the wine, allowing staff to observe or taste it. The lower tube component 830 can be adjusted to the extended state, and the adjusting screw 843 can be adjusted to the horizontal state. Rotating the lower pressing component 850 will drive the upper tube component 820 and the lower tube component 830 to rotate, thus agitating the fruit.
